How about changing the red asteroid belt mission icon to red so we can tell the difference between them:
Another question I want to ask about Magnetic Manipulator: Why it attacks with a different type of asteroids, like when it’s normal, it attacks with red asteroids and the opposite?
Also when Henelly’s Comet attacks up&down in high difficulties, it attacks even when the player isn’t under it, so I suggest to make it attack only if the player is under it so we can avoid that situation more.
